About the NVIDIA GeForce RTX 5090 Mobile GPU

The NVIDIA GeForce RTX 5090 Mobile is a mobile graphics card that launched in Q1 2025. It is built on the Blackwell 2.0 GPU microarchitecture (codename GB203) and is manufactured on a 5 nm process.

Memory

The RTX 5090 Mobile has 24 GB of GDDR7 memory, with a 1,750 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 896 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The RTX 5090 Mobile includes 10,496 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 990 MHz and can dynamically boost its clock speed up to 1,515 MHz. Complementing the processing units are 328 texture mapping units (TMUs) for efficient texture filtering and 112 render output units (ROPs) for pixel processing. Additionally, the GPU features 328 tensor cores optimized for AI-accelerated workloads and 82 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 95 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The RTX 5090 Mobile has the 16th best 3DMark 11 Performance GPU score among the 566 benchmarked GPUs in our database. It achieves 54.43% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 5090.

About the NVIDIA GeForce RTX 4090 Mobile GPU

The NVIDIA GeForce RTX 4090 Mobile is a mobile graphics card that launched in Q1 2023. It is built on the Ada Lovelace GPU microarchitecture (codename AD103) and is manufactured on a 5 nm process.

Memory

The RTX 4090 Mobile has 16 GB of GDDR6 memory, with a 2,250 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 576 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The RTX 4090 Mobile includes 9,728 CUDA cores, the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,335 MHz and can dynamically boost its clock speed up to 1,695 MHz. Complementing the processing units are 304 texture mapping units (TMUs) for efficient texture filtering and 112 render output units (ROPs) for pixel processing. Additionally, the GPU features 304 tensor cores optimized for AI-accelerated workloads and 76 RT cores dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The GPU has a thermal design power (TDP) of 120 W. A power supply not strong enough to handle this might result in system crashes and potentially damage your hardware.

Benchmark Performance

The RTX 4090 Mobile has the 22nd best 3DMark 11 Performance GPU score among the 566 benchmarked GPUs in our database. It achieves 49.89% of the performance of the best benchmarked GPU, the NVIDIA GeForce RTX 5090.
